Well, I was going to validate my CSS, and also had JavaScript code.
I got the error that I should first validate my XML, and that I had a <a that did not close. The problem was that <a was not a link, but code inside the JavaScript tag.
My advice to you is to make the validator simply ignore all code inside a <script> tag, or just ignore JavaScript.
That was all. Thank you.
Best wishes,
